Saw Palmetto and Minocycline

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Minocycline

Minocycline falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Saw Palmetto interacts with.

Saw palmetto might increase the risk of bleeding with anticoagulant or antiplatelet drugs.
Saw palmetto is reported to prolong bleeding time. Theoretically, it might increase the risk of bleeding when used concomitantly with anticoagulant or antiplatelet drugs.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's a little wrinkle with this pairing. The interaction in our file is really about saw palmetto and blood thinners, because saw palmetto has been reported (in a few scattered case reports) to lengthen bleeding time. Minocycline isn't a blood thinner, so it doesn't really fit that bleeding category. It's an antibiotic used for infections and acne, and it doesn't normally affect how your blood clots.

So for most people taking these two together, I wouldn't expect a meaningful bleeding problem from this combination alone. If you happen to also take an actual blood thinner like warfarin, aspirin, or clopidogrel, that's where the saw palmetto caution matters more. When in doubt, run your full list past your pharmacist or doctor.

From our pharmacist’s overview on the Minocycline page

“This is one of the longer interaction lists I review, and with minocycline it earns real care rather than a shrug. Most entries pair this tetracycline antibiotic, taken for acne and other infections, with supplements that raise bleeding risk, and a second sizable group, beer and wine included, can add strain on the liver.”

About Saw Palmetto

What is Saw Palmetto?

Saw Palmetto
  • Benign prostatic hyperplasia (BPH) symptoms
  • Urinary problems
  • Hair loss
  • Prostate health
  • Inflammation

Saw palmetto is a plant extract most often used for urinary symptoms linked to an enlarged prostate (BPH). The best research suggests it works no better than a placebo for most men, though it is generally well tolerated. Talk to your doctor or pharmacist before using it, especially for prostate or urinary problems that need proper evaluation.

About Minocycline

What Is Minocycline Used For?

Brand names: Vectrin, Dynacin, Minocin, Minocin IV, Solodyn, Acnamino MR, Minocin MR, Sebomin MR, Aknemin, Arestin Miscrosperes, Amzeeq, Zilxi

Oral and intravenous minocycline products treat many serious bacterial infections, including Rocky Mountain spotted fever, respiratory tract infections, sexually transmitted infections such as lymphogranuloma venereum and nongonococcal urethritis, plague, cholera, brucellosis, tularemia, and others caused by susceptible organisms. MINOCIN Intravenous is used when oral therapy is not adequate or tolerated.

Extended-release oral minocycline tablets are indicated specifically for inflammatory lesions of moderate to severe acne vulgaris in patients 12 years and older — not for treating infections. AMZEEQ (topical foam) treats inflammatory lesions of moderate to severe acne vulgaris in patients 9 years and older. ZILXI (topical foam) and EMROSI (oral capsule) are indicated for inflammatory lesions of rosacea in adults. ARESTIN (oral powder placed by a dental professional) is used alongside scaling and root planing to reduce pocket depth in adult periodontitis.
